25 July 2017: Six tropical cyclones active in the Pacific

A burst of cyclonic activity at two extremes over the vastness of the Pacific ocean in recent days has generated the six named tropical cyclones we see this Tuesday 25 July 2017!

Tropical Storm GREG, a strengthening and about to become major Hurricane HILARY, and an also strengthening Hurricane IRWIN are active, and moving away from land, off the Pacific coast of Mexico over the northern East Pacific. This makes it a total of nine named tropical cyclones  in the course of ten weeks in this quite active sub-basin for cyclogenesis.

Also on this day, more than 12,000  kilometers to the west, over the northwest Pacific, we see a strengthening Typhoon NORU and a decaying Tropical Depression KULAP to the west of Japan, a strong tropical wave designated as ‘Invest 99W’ by NOAA approaching the Philippines, and some 3.000 kilometers farther to the west Tropical Storm SONCA making landfall in Vietnam.

Quite a spectacle indeed, six named tropical cyclones and a possible seventh, all simultaneously active over the northern Pacific Ocean.

Closer to our neck-of-the-woods here in Florida, and the Gulf and Atlantic coastal regions the tropics are somewhat calm. There have been one off-season named tropical cyclone, ARLENE, in April, and three named storms since the ‘official’ start of the 2017 Atlantic Hurricane Season, including short-lived Tropical Storm DON, which perished over the southeastern Caribbean just last week.

So, busy there, relatively quiet here, however we should keep in mind this is the time of the year when the northern tropics get busy with cyclonic activity. Get ready! Be prepared! MITIGATE!

16 October 2016: The northern tropics remain restless, watch out!

The Autumn equinox in the northern hemisphere has come and gone, and as the Sun marches south of the equator overhead the southern hemisphere tropics we have started to see tropical waves and storm cells flare-up on that half of the planet.

Soon the northern hemisphere hurricane, typhoon and cyclone seasons will start to wind down and cease menacing hundreds of million of residents of coastal regions and island nations in the Atlantic, the Pacific and the Indian oceans.

We  in the northern hemisphere must however remain alert and be prepared, for the ‘official’ tropical cyclone seasons may end on fixed dates, but the reality is that Mother Nature will always do as she will!  Also, ocean heat content has continuously grown higher as every new year becomes the warmest of record or one of the warmest. So, conditions for tropical cyclone development have become earlier-happening, longer-lasting and wider-spread over time.

In fact, satellite imagery this morning brought pictures of a large tropical disturbance over the Bahamas looking suspiciously as if cyclonic development could be possible. This may already be affecting a wide region from Florida to the Carolinas, which were hit hard a few days ago by Hurricane MATTHEW, and also suffered a remote hit that coincided with King Tides from passage of Hurricane NICOLE at a distance.

Other satellite images of the north Atlantic basin show a tropical wave over the isthmus of Panama, another one in the middle of ‘hurricane alley’ and yet another one beginning to emerge over the eastern Atlantic from equatorial Africa, plus a nice one of Hurricane NICOLE still going strong over the open waters of the Atlantic.

Farther east from the eastern Atlantic waters, there remains a long train of tropical waves and storm cells over equatorial Africa reaching all the way to Lake Victoria and beyond. Plenty of fuel left for future cyclonic activity.

On the opposite side of the planet, near northwest Pacific waters there is typhoon SARIKA moving in the South China Sea toward another landwall after ravaging the Philippines, while to the east there is a strong typhoon HAIMA approaching the Philippines Sea and a possible double-whammy on that most cyclone-vulnerable country on Earth.

Life goes on, and this is the only planet we have for now, so it is prudent to pay attention, remain alert, and be prepared alway. MITIGATE!
